' overlapping ridge pole sections.

also provided with metallic straps 14 having downturned ends which overlap the channel bar 5 at the upper ends of the side wall units B. The'webs of the long channel bars 5 are bent downwardly forming abutment legs 15 to overlap the vertical edges of the endmost side wall units B as shown in Fig. 11 to hold said units from endwise movement and the inside flanges of said channel bars are cut away at 16, (Fig. IV), to permit said endmost side wall units to engage the adjacent end wall units 13'.

To unite the middle portion of the roof frame to the side wall units, the ends of the intermediate rafter section C are provided with metal straps 17 having downturned flanges which overlap the wall units B (see Figs. I and V).

The ridge pole D is arranged between the upper ends of the rafters 9, and seated on the metal straps 11. To interlock the ridge pole with the rafter sections, pins 18 are secured to the ridge pole so as to embrace straps 11 and at the ends of the ridge pole I attach small metal plates 18 which extend downwardly to a point below the metal straps 11 on the end rafter sections. The ridge pole is preferably composed of two sections, which overlap each other at the middle of the roof, and the pins 18 at this point serve as dowels for connecting the (See Fig.

Horizontal longitudinal braces 19 provided with fingers 20 rest upon and abut against the tie beams 10 to stiffen the roof structure. The rafter sections are adinstably connected by diagonal tie wires 21 which are tightened after the roof structure elements are assembled, thereby forcing the transverse tie beams of the rafter sections against the ends of the braces 19.

The various sections of my tent frame may be very easily assembled ortaken apart, and when thetent frame is to be packed for shipment, the floor sections may be utilized as a crate for inclosing the wall units, rafter sections, ridge pole sections, and the horizontal braces 19.

I claim '1. A portable tent frame comprising side and end wall units abutting against each other, a roof frame seated on said unitschannel shaped members secured to the roof frame and straddling the top corners of said end wall units, and bars secured to the corners of the roof frame and overlapping the side wall units, the said bars and members thus cooperating to interlock the roof frame with the side and end wall units.

2. A portable tent frame, comprising floor units ab utting against each other and having short Slll sections, channel shaped pocket members straddling said short sill sections and overlapping their abutting ends, each of said pocket -members having an upturned outer flange, an abutment strip secured to said floor'units, and wall units seated on said floor units between said flanges and abutment strips.
